5-fluoro-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carbonitrile CAS NO.:1350653-26-7

Core Precursor in Pharmaceutical R&D
As a fluorine-containing pyrazolopyridine scaffold molecule, it can be used to develop targeted drugs, especially in the fields of anti-tumor (e.g., inhibiting the activity of specific kinases, blocking tumor cell proliferation) and anti-infection (targeting key proteins of bacteria or viruses). The fluorine atom modification enhances the molecule's binding affinity to targets and its metabolic stability in vivo, making it a crucial structural unit in the early R&D of innovative small-molecule drugs. 
Building Block for Bioactive Molecule Synthesis
Through derivatization reactions (such as hydrolysis, coupling, cyclization) of active groups like cyano and fluorine atoms, it can be used to construct derivatives with specific biological activities. These derivatives are applied in screening candidate compounds with functions such as anti-inflammation and immune regulation, providing a key molecular template for the research of "structure-activity relationship" in drug discovery.
Intermediate for Organic Heterocycle Synthesis
In the field of heterocyclic chemistry, it serves as a key intermediate for synthesizing more complex pyrazolopyridine derivatives. By modifying the benzene ring, pyrazole ring, or cyano group, a diverse library of heterocyclic molecules can be constructed. This provides basic molecules with diverse structures for subsequent research in materials science (e.g., functional small-molecule fluorescent materials) or the pharmaceutical field.
Terminology Explanation
Targeted drugs: Translated directly as "targeted drugs", the standard term in pharmacology referring to drugs that act on specific biological targets (e.g., kinases, viral proteins) related to diseases.
Derivatization reactions: "Derivatization reactions" is the professional expression in organic chemistry, referring to chemical reactions that convert a compound into its derivative (e.g., hydrolyzing cyano to carboxyl).
-Structure-activity relationship (SAR): The abbreviation "SAR" is retained after the full name "structure-activity relationship"-a core concept in medicinal chemistry, describing the correlation between a molecule's structure and its biological activity, which is widely used in English academic and industrial contexts.
